To all whom it may concern: i

Be'it known that I, FkA NfiTRINKfimanlli facturer, citizen ofthe Duchy of Brunswick, Empire of -Germany,.- residingat 'Bruns. wick, Germany, have invented certain new and useful Improvements in Carrying Mechanisms for"Calciilating-lvlachines, of which the following is a specification.

My invention relates to limprovementsin carrying mechanisms for calculating .machines, and more particularly in carrying mechanisms in which the carrying operation is performed by-means of disks located in front of the numeral wheels and taking part v in the rotation of the latter." If in such mechanisms a numeral wheel. passes from its nine position to its, zero position, or vice versa, it shifts abutment members into 'the path of coiip'erating' teeth provi.ded"on the disk, whereby the numeral wheel of the next higher order is shifted forward or backward a distance corresponding to one digit. Carrying mechanisms. of this type are suitable for use in combination with the main registering mechanism as well as with the revolutions counting mechanism of, calculating machines of diffe ent constructions.

My invention consists in the matters deout in the appended claims.

" 1to5 is the drawings, a shaft '24. which is adapted to be rotated by a crank-23 carries 'a plurality of setting disks 25 which are provided with radially shiftable teeth 26 adapted to be shifted into or out of opera tive positions by cam disks 27, one cam diskbeing provided for each of the settingdisks The cam disks are provided with finger pieces 28 projecting through'slots "29 of the cover 29 of the casing of-the machine. "In front of the disks 25 and 27 which constitu'te the setting mechanism a carriage 30 is mounted in suitable guides-32 in the base plate 31 of the machine, which carriage is I adapted to be shifted in adirection parallel with shaft '24: of the setting mechanism. on

the carriage a shaft 10 is mounted which is parallel with the shaft 24 and carries a plurality of numeral wheels 1 provided about .their circumferences with the characters from 1 to 9 and the zero sign and constituting the registering mechanism. Each of the-disks 1 is equipped with spur gears 12 adapted to be engitged when turning the crank 23 by the th 26 of the co operating setting vdisk 25, so that the numeral wheels 1 are turned forward or backward distances corresponding to the numbers set up on the setting disks.

Onthe carriage 30 a revolutions counting mechanism 11 is mdunted coaxially of the registering mechanism 1. The said revolution's counting mechanism is adapted to be operated once for each operation of the crank, by means of a single tooth wheel 33, which turns the said revolutions counting mechanism one value forward or backwards The mechanisms 1 and 11 are equipped with resetting devices of any known or pre-' ferred construction. To show what may be done, the shafts 10 and 34' are provided with wing nuts 35 and 36, and with pins 10 and 34:. When turning the wing nuts the plus 10 and 34"er'1gage noses 1 andsll in the numeral wheels 1 and llrespectively and return the same into their zero positions.

As is shown most clearly in Figs. 3 to 5,

'- each of the numeral wheels 1 is provided at its left side' with a slide 2 which is adapted to be shifted against the action of'a-spring 4 by an abutment such as a pressure roller 3 located adjacent to the wheel 1, so that a finger 5 which projects from the inner end of the slide 2-to the left is moved toward the v periphery of the wheel. The finger 5- is so long that it is adapted to transmit the movement imparted'the'reto by the abutment 3 to the adj acent numeral wheel, as is shown in Fig. 5; At the right hand side each numeral wheel'l is equipped. with ten teeth 6 which are. adapted to be projected radially, and which are uniformly distributed according to the characters provided about the eircumferences of the numeral wheels. The parts are so arranged, that in the regular '.positions of the numeral wheels 1 each finger 5 can engage the enlarged inner end i of a tooth 6 of the adjacent wheel, when it is shifted outward by' the cooperating abutment 3. The ten teeth 6 are held in either one of their end positions bya spring actu-' ated locking ring 7 which engages in notches 8 or 9 of the teeth 6, as is shown in Figs. 4 and 5. YVhen a tooth 6 is shifted beyond the circumference of the numeral wheel 1, it projects into the path of a tooth 37 which is provided on a disk 38 disposed in the same plane with the numeral wheel and taking part in the rotation of the shaft 24 of the setting mechanism. The tooth 37 engages the projected tooth 6 and advances the corresponding numeral wheel .1 a distance corresponding to one digit. At the end of the shifting operation the projected tooth 6 is engaged by a stationary cam 17 providedat a suitable part of the machine and adapted to force the said tooth backward and away from thecircumference of the numeral wheel 1. The said cam is provided with two operative faces according to the two directions of rotation of the numeral wheel 1, as is shown in Fig. 2. Each of the disks 38 is provided with two teeth 37 corresponding to the two directions of the revolution of the shaft 24 (Fig. 2.). As is shown in Fig. 1, in all the disks 38 the teeth 37 which are operative for the same direction of rotation of the crank shaft-are distributed on the disks according to a helical line, so that they are successively thrown into operation according to the successive carrying operations.

In the construction shown in F igs.. 6 and 7 rocking teeth are provided instead of the radially shiftable teeth shown in Figs. 1 to 5. At the right side of the numeral wheels 1 ten teeth 14 are provided which have rocking supports on pins 13 and are locked in their end positions by spring actuated pins 18. When shifting one of the laterally projecting fingers 5 the corresponding tooth 14 is rocked upward, the finger 5 acting on a finger 16 of the tooth. The carrying operation is the same as has been described with reference to Figs. 1 to 5 by means of teeth 37 provided on disks 38. For returning 'the teeth into inoperative positions cams z are provided the construction and operation of which are similar to those of the cams -17 shown in Figs. 1 to 5.

--Instead of the. special disks 38 and 38' shown in Figs. 5 and 7 the well known setwill readily be understood without illustra- V tion. Furthermore in my improved carrying mechanism. the well known rockable carrying teeth on the setting disks 25 may be used in their rocked positions or in their inoperative positions (see for example teeth 67 of the machine shown in United States Letters Patent- No. 1,040,059 granted to me October 1, 191-2). In order to have a reliable operation I prefer to lock the said teeth during the carrying operation in their rocked positions. As shown in Fig. 8 where the well known carrying teeth 67 perform the carrying operation in their rocked positions by acting on teeth 6, this locking may be efi'ectedby cam faces 39. If desired instead of the slide 2 a rocking lever may be provided.

Preferably the cam faces 17 are beveled at both sides, as is shown in Figs. 2 and 4, so that the teeth 6 are forced backward also in such cases in which they are shifted outward at other places by reason of irregular operation of the locking mechanism. Such constructions are also shown in Figs. 9 and 10. If at any improper time a tooth is shifted beyond thecircumference of the disk, it is returned into-inoperative position before it is brought into position for performing a carrying operation. In the construction shown in Fig. 9 each of the cams 17 is also provided with a cam face 17 at the side which is opposed to the point at which the teeth 6" are struck by the tooth 37, and the said cam faces 17 are so shaped, that they force any tooth 6 backward and into the numeral wheel 1, which might accidentally be projected beyond the periphery of the numeral wheel 1 and approaches the point a: and this is done before the tooth arrives at the point a2. Each of the cams 17 is stationary relatively to the numeral wheel and its parts are located symmetrically of a diameter of the said wheel. Preferably the cams 17 are arranged in such a way, that when a tooth 6 is being shifted outward the points y at which the cam faces 17 and 17 intersect are located adjacent to the teeth 6' which adjoins'the said tooth 6' being shifted. In this case the said points lock the adjoining teeth against being simultaneously projected. I In the example shown in Fig. 10 the cams which act in both directions are constructed in the form of levers 21 having rocking supports at 20. The heads 21 of the said levers are beveled at both sides and their points 21 are directed toward the tooth 37" performing the shifting operation, so that the I said heads can be shifted by'the said tooth to the side against the. action of the springs 22, whetherthe crank of the machine is being turned forward or backward. The levers 21 are constructed in .such a way, -that when they arebein shifted. to the side as described their hea s 21 move radially t-v ward the numeral wheel 1 and strike in the manner of'hammers onthe projecting tooth 6 and force the same backward and intoits disk. r

In the construction shown in Figs. 1 to 5 much diflicultyis met with when provid-.

ing means for locking the radially shiftable teeth in their end or operative and inoperativ'e positions, because by reason of the small size of the numeral wheels very little space is available for the locking means. In the construction shown in Fig. .9 this difficulty is avoided by providing a locking ring 7 which is common to allthe teeth 6, and which is forced by spring action into engagement with either one of no'tches8' and -9' of the teeth 6, so as to lock the teeth in their end positions. Such a ring requires a -minimum of space, and itmay'be disposed at the side of. the numeral wheel, where it iseasily accessible. In this "construction the .ring 7 has a rocking movement about the axis of the numeral wheel 1-", and'it is formed at its front face wi'th beveled noses 7' adapted to. engage in beveled notches 8 or 9 of the teeth 6. 'By means of two springs 19 which are diametrically opposed to each other the ring is forced into engage ment with. either one of the notches. If a tooth 6 is forced outward or inward rei spectively by a member, such as finger 5 or 5 shown in Figs. 5'and 7 engaging at the rear of the inner end 6 of the tooth, or a cam 17- located adjacent to, the numeral wheel, the-ring 7 yields against the'pressure of the springs '19 and permits it's nose 7 to disengage the notch of the tooth 6?. In this operationthe ring 7 rocks aboutjthe axis 0 the numeral wheel, while being guided'by pins 41 secured to the'numeral wheel, and 1t return: into the position shown'in the h ure, when the tooth 6' arrives in. its new en sition. While the ring 7 is being rocked all the teeth 6' are released] If one of the teeth which are remote from the pointw should be shifted beyond the circumference of the nuineral wheel, no harm is done, because the cams 17, which are operative in both directions force'the saidtooth backward and into the disk before it reaches its operative position at point m. If desired special means may be provided for preventing the teeth from being accidentally shifted. To show what may be done a covering plate 42-is provided'. which closely encircles the numeral wheel 1, and is open at the operative part :0, as is illustrated in Fig.11. The breadth of the plate 42 is such, that neither the shiftable slide 2 nor the characters from 0 9 progided about the circumference are covere I claim herein as my invention:
